OAUTH Client Credentials Implementation

Hi

I have a resource in my Integration and the requirement is to use Oauth2.0 for accessing the resource. The resource would be accessed by another application(not end user), IS acts as both resource server and authorization server. We are considering to use the client credentials grant for the same.

But from IS Admin guide, I can find that only auth code grant and implicit grant are supported. Has some one used Client Credentials Oauth Grant and secured REST end points?

Thanks in advance,
